hope this helps!!:)
Step-by-step explanation:
First, you have to give each a variable. In this case, the smaller number will be x and the larger number will be y.
Next, you need to make the equations. Your equations are:
y+3x=14
x+2=y
What you're solving for is y because the questions asks what the larger number is.
Then, substitute. It will be this after substituted:
x+2+3x=14
Combine like terms.
4x+2=14
Subtract by 2 on both sides.
4x=12
Divide by 4 on both sides.
x=3
^This what your smaller number is but you can easily find what y (the larger number) is. Substitute x into the other equation, which is basically adding 2 to 3.
y=5
